How do you calculate the greatest common factor?

To find the greatest common factor (GCF) between numbers, take each number and write it’s prime factorization. Then, identify the factors common to each number and multiply those common factors together.

### How do you factor out the GCF?

Factoring out the GCF is the first step in many factoring problems. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term.

### What is the GCF of fractions?

GCF = 1/24. GCF is a fraction smaller than both the fractions or equal to one or both of them (when both fractions are equal). When you take the GCF of the numerator and LCM of the denominator, you are making a fraction smaller than (or equal to) the numbers.

What are the factors of GCF?

The GCF of two numbers is the largest factor of the two numbers. For instance, find GCF of 16 and 24 written as GCF (16,24). The factors for 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The largest factor for both numbers have in common is 8, so GCF (16,24) = 8. The factors for 7 are 1 and 7.
